Technical Field

[0001] This utility model belongs to the field of conveyor technology, and in particular relates to a belt cleaning device for a belt conveyor. Background Technology

[0002] During operation, belt conveyors are usually equipped with cleaning devices at the redirecting rollers to clean the material on the belt and prevent it from being carried back to the return section, causing the material to spill along the way.

[0003] Regarding belt cleaning devices for belt conveyors, a search reveals that a utility model patent with Chinese patent authorization announcement number CN207482794U discloses a belt conveyor cleaner, such as... Figure 1 As shown, it mainly includes a support a, on which multiple connecting frames b are provided, and a scraper c is provided on the top of the connecting frame b.

[0004] In the actual implementation of existing conveyor cleaning devices with similar technical solutions as described above, there are areas that need improvement: if the scraper is in hard contact with the belt, and the scraper is too tight when scraping materials, it can easily cause the belt to tear. Utility Model Content

[0005] In view of the shortcomings and defects in the existing technology, the purpose of this utility model is to provide a belt cleaning device for a belt conveyor, which solves the problem that in the existing belt cleaning devices, the scraper is in hard contact with the belt, and if the scraper is too tight when scraping materials, it is easy to cause the belt to tear.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a belt cleaning device for a belt conveyor, including a scraper and two supports arranged on the left and right sides of the conveyor bracket. Each support is connected to a support plate that can be raised and lowered. A rotatable and adjustable round rod is connected between the two support plates. A fixing plate is inclinedly fixed on the round rod. Multiple rubber blocks are fixed on the fixing plate. An inclined plate is fixed to the rear side of each rubber block. An inclined frame is detachably connected to the upper rear side of the inclined plate. A support plate is detachably connected to the upper rear side of the inclined frame. A slot is provided on the rear side of the top of each support plate. The scraper is detachably connected and installed in the slot of the support plate.

[0007] As a further improvement of this utility model, the support is provided with an elongated hole running vertically, and the support plate is connected to the elongated hole on the support by fastening bolts.

[0008] As a further improvement of this utility model, the round rod is rotatably connected to the support plate, and each end of the round rod is provided with a locking device that can lock the round rod to the support plate.

[0009] As a further improvement of this utility model, each of the locking devices includes an adjusting rod, which is fixed to the end of the round rod. The support plate is provided with an arc-shaped hole, and the adjusting rod is provided with a locking bolt that can be fixed in the arc-shaped hole.

[0010] As a further improvement of this utility model, an elastic scraper is provided on the rear side of the inclined plate.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] 1. By setting up supports, support plates, and scrapers, this device is connected to the conveyor support via supports. The round rod, fixed plate, rubber block, inclined plate, inclined frame, and support plate can support the scraper. The rubber block allows the scraper to have a certain degree of buffering elasticity and adjustment, avoiding the problem of belt tearing caused by a rigid scraper, or incomplete cleaning caused by an excessive gap between the scraper and the belt. In addition, by setting up multiple support plates and scrapers, compared with a structure with a single scraper, each scraper can have a certain degree of self-adjustment, resulting in better self-adjustment force, improved cleaning ability, and prevention of belt scratches.

[0013] Furthermore, by adjusting the height of the support plate on the support, the height of the scraper can be adjusted. The round rod is also adjustable on the support plate, so rotating the round rod can adjust the angle of the scraper, allowing the scraper to better fit the belt and improve the cleaning effect.

[0014] 2. By rotatably connecting the round rod to the support plate and providing a locking device at the end of the round rod, the round rod can be adjusted by rotation and then locked to the support plate by the locking device, making it convenient to adjust the scraper.

[0015] 3. By installing elastic scrapers on the rear side of the inclined plate, the elastic scrapers can also clean the belt from below, forming two cleaning lines and improving the cleaning effect. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 2-3 The present invention will be described in further detail below. For clarity, only the structures relevant to the inventive features of the present invention are shown in the figures.

[0022] For ease of description, the coordinate system is defined as follows: Figure 2 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0023] This utility model discloses a belt cleaning device for a belt conveyor. (Refer to...) Figure 2 and Figure 3 A belt cleaning device for a belt conveyor includes a scraper 1 and two supports 2, which are mounted on the left and right sides of a conveyor frame. The upper ends of the supports 2 can be welded or bolted to the conveyor frame. Each support 2 is connected to a height-adjustable support plate 3. Specifically, the support 2 has an elongated hole 10 running vertically, and the support plate 3 is connected to the elongated hole 10 on the support 2 by fastening bolts, so the height of the support plate 3 can be adjusted vertically.

[0024] like Figure 2 As shown, a rotatable and adjustable round rod 4 is connected between the two support plates 3. Specifically, the round rod 4 is rotatably connected to the support plate 3, and each end of the round rod 4 is provided with a locking device that can lock the round rod 4 to the support plate 3, such as... Figure 3 As shown, each of the locking devices includes an adjusting rod 11, which is fixed to the end of the round rod 4. The support plate 3 has an arc-shaped hole 12, and the adjusting rod 11 is provided with a locking bolt 13 that can be fixed in the arc-shaped hole 12. Therefore, after adjusting the round rod 4 by rotating it, the round rod 4 is locked to the support plate 3 by the locking device, which facilitates the adjustment of the scraper 1.

[0025] like Figure 2 As shown, a fixing plate 5 is welded and fixed to the round rod 4 at an incline. Multiple rubber blocks 6 are fixed on the fixing plate 5. An inclined plate 7 is fixed to the rear side of each rubber block 6. An inclined frame 8 is detachably connected to the upper rear side of the inclined plate 7 by bolts. The inclined frame 8 is arc-shaped. A support plate 9 is detachably connected to the rear side of the upper end of the inclined frame 8 by bolts. A slot is provided on the rear side of the top of each support plate 9. The scraper 1 is detachably connected to the slot on the support plate 9 by bolts.

[0026] In addition, an elastic scraper 14 is provided on the rear side of the inclined plate 7; therefore, the elastic scraper 14 can also clean the belt on the lower side, forming two cleaning lines to improve the cleaning effect.

[0027] This invention, by setting up a support 2, a support plate 3, and a scraper 1, connects the device to the conveyor support via the support 2. The round rod 4, fixed plate 5, rubber block 6, inclined plate 7, inclined frame 8, and support plate 9 support the scraper 1. The rubber block 6 provides the scraper 1 with a certain degree of buffering and elastic adjustment, preventing the scraper 1 from being rigidly set, which can easily cause belt tearing when the scraper 1 is too tight, or incomplete cleaning due to excessive gap between the scraper 1 and the belt. In addition, by setting up multiple support plates 9 and scrapers 1, compared with a structure with a single scraper 1, each scraper 1 can perform a certain degree of self-adjustment, resulting in better self-adjustment force, improved cleaning ability, and prevention of belt scratches.

[0028] Furthermore, by raising and lowering the support plate 3 on the support 2, the height of the scraper 1 can be adjusted by adjusting the height of the support plate 3. The round rod 4 is rotatably adjustable on the support plate 3, so rotating the round rod 4 can adjust the angle of the scraper 1, thereby enabling the scraper 1 to better fit on the belt and improve the cleaning effect.
